Description

切削用前端工具Cutting end tools

本發明涉及一種切削用前端工具。The present invention relates to a cutting end tool.

作為在鋼板等開孔、或調整該孔的直徑的前端工具，存在鑽頭。例如，分級鑽頭是開設各種直徑的孔的鑽頭，鉸刀是調整由鑽頭鑽好的孔的直徑的鑽頭。這種切削工具存在手動用和電動用。電動用的鉸刀成為可安裝於衝擊扳手等電動工具的結構。作為可向衝擊扳手安裝的結構，例如，存在專利文獻1所記載的結構。As a tip tool for drilling a hole in a steel plate or the like, or for adjusting the diameter of the hole, there is a drill. For example, a grader drill is a drill for opening holes of various diameters, and a reamer is a drill for adjusting the diameter of the hole drilled by the drill. Such cutting tools exist for manual and electric use. The electric reamer has a structure that can be attached to electric tools such as impact wrenches. As a structure which can be attached to an impact wrench, for example, there exists the structure described in patent document 1.

專利文獻1所記載的連接構造(以下稱為「轉接器」。)具備：收納部，其通過將驅動旋轉工具的***角***而收納***角；和固定部，其設置於與收納部的開口相反的那一側的面，用於固定切削構件。固定部成為外螺紋，與作為切削構件的分級鑽頭的內螺紋螺紋結合。 先前技術文獻 專利文獻The connection structure (hereinafter referred to as "adapter") described in Patent Document 1 includes: an accommodating part for accommodating the insertion angle by inserting the insertion angle of the driving rotary tool; and a fixing part provided on the accommodating part. The face on the opposite side of the opening is used to fix the cutting member. The fixed portion is a male thread, and is threadedly coupled to the female thread of the graded drill as a cutting member. prior art literature Patent Literature

專利文獻1：日本特開2015-223659號公報Patent Document 1: Japanese Patent Laid-Open No. 2015-223659

發明欲解決之問題The problem to be solved by the invention

專利文獻1的轉接器以固定部的螺紋牙處於與切削構件的旋轉方向相反的方向的方式設置，在切削加工中切削構件的內螺紋和固定部(外螺紋)以相互緊固的方式起作用。因此，在切削加工中，始終擰緊。在專利文獻1中，提及無論驅動旋轉工具正轉還是反轉，固定部與切削構件之間的固定都不減弱這樣的方法，但未提及解除固定部與切削構件之間的固定的結構。因此，專利文獻1的發明在開孔加工結束後難以從轉接器的固定部拆卸切削構件。The adapter of Patent Document 1 is provided so that the thread of the fixing portion is in a direction opposite to the rotational direction of the cutting member, and the female thread of the cutting member and the fixing portion (external thread) are fastened to each other during cutting. effect. Therefore, in cutting operations, always tighten. Patent Document 1 mentions a method in which the fixing between the fixing portion and the cutting member is not weakened regardless of whether the rotary tool is driven to rotate forwardly or reversely, but does not mention a structure for releasing the fixing between the fixing portion and the cutting member . Therefore, in the invention of Patent Document 1, it is difficult to remove the cutting member from the fixing portion of the adapter after the drilling process is completed.

不過，只要能夠更換安裝於轉接器的切削主體部，即為有用。其原因在於，例如，能夠更換成種類不同的鑽頭刃(分級鑽頭、鉸刀的鑽頭刃)，或者，在鑽頭刃破損了的情況下，能夠更換鑽頭刃部分。因此，需要具備即使假設在切削主體部擰緊到轉接器的情況下也能夠容易地拆卸這樣的機構。However, it is useful as long as the cutting body part attached to the adapter can be replaced. This is because, for example, it can be replaced with a different type of drill edge (a graded drill, a drill edge of a reamer), or when the drill edge is damaged, the drill edge portion can be replaced. Therefore, it is necessary to provide a mechanism that can be easily detached even if the cutting body is screwed to the adapter.

因此，本發明的目的之一在於提供一種如下切削用前端工具：切削主體部和將切削主體部安裝於旋轉工具的轉接器可拆裝，且可從轉接器容易地拆卸切削主體部。 解決問題之手段Therefore, an object of the present invention is to provide a cutting tip tool in which a cutting body portion and an adapter for attaching the cutting body portion to the rotary tool are detachable and the cutting body portion can be easily detached from the adapter. means of solving problems

***孔12可供衝擊扳手50的***角51***，該***孔12沿著中心軸線P1形成。The insertion hole 12 can be inserted into the insertion corner 51 of the impact wrench 50, and the insertion hole 12 is formed along the central axis P1.

槽13是沿著以中心軸線P1為中心的周向的環狀，形成於主體部11的第1端部的外周面。圖1所示的O形環2嵌入該槽13。The groove 13 has an annular shape along the circumferential direction with the center axis P1 as the center, and is formed on the outer peripheral surface of the first end portion of the main body portion 11 . The O-ring 2 shown in FIG. 1 is inserted into this groove 13 .

第1貫通孔14A形成為沿著以中心軸線P1為中心的徑向從***孔12向槽13貫通。第2貫通孔14B形成為沿著徑向從***孔12向槽13貫通。如圖3所示，第1貫通孔14A和第2貫通孔14B以中心軸線P1為中心而位於彼此相反的一側的位置，且位於同一直線上。第1貫通孔14A和第2貫通孔14B具有能夠供要******角51的銷***孔52的銷***的大小。The first through hole 14A is formed so as to penetrate from the insertion hole 12 to the groove 13 along the radial direction with the center axis P1 as the center. The second through hole 14B is formed to penetrate from the insertion hole 12 to the groove 13 in the radial direction. As shown in FIG. 3 , the first through-hole 14A and the second through-hole 14B are located on the opposite sides with the center axis P1 as the center, and are located on the same straight line. The first through-hole 14A and the second through-hole 14B have a size capable of inserting a pin to be inserted into the pin insertion hole 52 of the insertion corner 51 .

在將轉接器10安裝於衝擊扳手50的情況下，以形成沿著徑向的一串的孔的方式使***角51的銷***孔52與第1貫通孔14A和第2貫通孔14B一致，***角51***轉接器10的***孔12。並且，銷***於該一串的孔。O形環2(參照圖1)嵌入槽13，以便防止已***到一串的孔的銷脫落。When the adapter 10 is attached to the impact wrench 50, the pin insertion holes 52 of the insertion corners 51 are aligned with the first through holes 14A and the second through holes 14B so as to form a series of holes along the radial direction. , the insertion corner 51 is inserted into the insertion hole 12 of the adapter 10 . And a pin is inserted in this series of holes. O-rings 2 (refer to FIG. 1 ) fit into grooves 13 to prevent the pins inserted into the series of holes from falling out.

此外，設置於主體部11的第1端部的連接部只要是能夠相對於衝擊扳手的***角51安裝的結構，就不限定於上述結構，若物件方是除了衝擊扳手以外的旋轉工具，則可根據該物件方的結構適當變更。In addition, the connection part provided at the first end of the main body part 11 is not limited to the above-mentioned structure as long as it can be attached to the insertion angle 51 of the impact wrench. If the object is a rotating tool other than an impact wrench, It can be appropriately changed according to the structure of the object.

在主體部11的第1方向上的第2端部設置有孔(第2孔)15，該孔(第2孔)15沿著第1方向延伸，且在內周面形成有螺紋槽(第1螺紋槽)15A。圖5是從第1方向觀察轉接器10的第2端部側的平面圖。後述的切削主體部20***於該孔15，切削主體部20利用螺紋作用固定於孔15。孔15以在第1方向上與***孔12重疊的方式沿著中心軸線P1形成。另外，孔15與***孔12相連。因此，在切削主體部20***於孔15時，能夠從***孔12側視覺辨認切削主體部20的端面。A hole (second hole) 15 is provided at the second end portion in the first direction of the main body portion 11, the hole (second hole) 15 extends along the first direction, and a screw groove (second hole) is formed on the inner peripheral surface. 1 thread groove) 15A. FIG. 5 is a plan view of the second end portion side of the adapter 10 viewed from the first direction. The cutting body 20 described later is inserted into the hole 15 , and the cutting body 20 is fixed to the hole 15 by a screw action. The hole 15 is formed along the central axis P1 so as to overlap the insertion hole 12 in the first direction. In addition, the hole 15 is connected to the insertion hole 12 . Therefore, when the cutting body portion 20 is inserted into the hole 15 , the end face of the cutting body portion 20 can be visually recognized from the insertion hole 12 side.

接著，對要***於轉接器10的孔15的切削主體部20進行說明。Next, the cutting body portion 20 to be inserted into the hole 15 of the adapter 10 will be described.

圖6是切削主體部20的從轉接器10拆掉後的狀態的平面圖。FIG. 6 is a plan view of a state in which the cutting body portion 20 is removed from the adapter 10 .

切削主體部20是沿著中心軸線P2延伸的棒狀。以下，將沿著中心軸線P2的方向稱為第2方向。在切削主體部20的第2方向上的第1端部的外周面設置有螺紋槽(第2螺紋槽)21。對於該螺紋槽21和轉接器10的螺紋槽15A，一個是外螺紋，另一個是內螺紋。並且，切削主體部20，藉由其第1端部***於轉接器10的孔15，螺紋槽21與轉接器10的螺紋槽15A嵌合，而固定於轉接器10。此外，在將切削主體部20安裝到轉接器10的情況下，中心軸線P1與中心軸線P2一致。也就是說，在將切削主體部20安裝到轉接器10的狀態下，第1方向與第2方向一致。The cutting body portion 20 is in the shape of a rod extending along the central axis P2. Hereinafter, the direction along the central axis P2 will be referred to as a second direction. A thread groove (second thread groove) 21 is provided on the outer peripheral surface of the first end portion of the cutting body portion 20 in the second direction. As for the thread groove 21 and the thread groove 15A of the adapter 10, one is an external thread and the other is an internal thread. Then, the cutting body 20 has its first end inserted into the hole 15 of the adapter 10 , and the screw groove 21 is fitted into the screw groove 15A of the adapter 10 , and is fixed to the adapter 10 . Further, when the cutting body portion 20 is attached to the adapter 10, the central axis P1 and the central axis P2 coincide. That is, in a state where the cutting body portion 20 is attached to the adapter 10, the first direction and the second direction coincide.

圖7是從第2方向觀察切削主體部20的第1端部側的平面圖。在切削主體部20的第1端部側的端面設置有螺紋孔22。在圖中示出有螺紋孔22是一字槽(縫)的例子。如上述那樣，在切削主體部20***於孔15時，能夠從***孔12側視覺辨認切削主體部20的端面。因此，在將切削主體部20安裝到轉接器10的狀態下，藉由從***孔12***一字螺絲起子，能夠使一字螺絲起子與螺紋孔22嵌合。並且，藉由利用一字螺絲起子使切削主體部20旋轉，能夠從轉接器10拆卸利用螺紋作用固定到轉接器10的切削主體部20。由此，例如，在從轉接器10拆卸切削主體部20之際，即使是在螺紋彼此嚙合而難以拆卸的情況下，或者，即使是在切削過程中切削主體部20被折斷而僅切削主體部20的螺紋槽21部分殘留到轉接器10的孔15內的情況下，也能夠使用一字螺絲起子而從轉接器10拆卸切削主體部20。FIG. 7 is a plan view of the first end portion side of the cutting body portion 20 viewed from the second direction. A screw hole 22 is provided on the end surface of the cutting body portion 20 on the side of the first end portion. In the figure, there is shown an example in which the screw hole 22 is a slot (slot). As described above, when the cutting body portion 20 is inserted into the hole 15 , the end face of the cutting body portion 20 can be visually recognized from the insertion hole 12 side. Therefore, by inserting a flat-blade screwdriver from the insertion hole 12 in a state where the cutting body 20 is attached to the adapter 10 , the flat-blade screwdriver can be fitted into the screw hole 22 . Furthermore, by rotating the cutting body portion 20 with a flat-blade screwdriver, the cutting body portion 20 fixed to the adapter 10 by the screw action can be removed from the adapter 10 . Thus, for example, when the cutting body 20 is detached from the adapter 10, even if the threads are engaged with each other and it is difficult to detach, or even if the cutting body 20 is broken during cutting, only the cutting body Even when a portion of the thread groove 21 of the portion 20 remains in the hole 15 of the adapter 10 , the cutting body portion 20 can be removed from the adapter 10 using a flat-blade screwdriver.

此外，在上述的說明中，列舉一字槽(狹縫)的例子作為螺紋孔22，但作為螺紋孔22，除了一字槽之外，可列舉出十字槽(十字孔)、六角孔、四方孔、星形孔(六角星)等公知的螺紋孔。只要是設置有這些螺紋孔的切削主體部20，就能夠利用與這些螺紋孔相對應的刀頭、扳手，使用手工作業工具或電動工具(衝擊扳手、衝擊螺絲起子等)並利用螺絲起子、六角扳手其他手工工具、電動螺絲起子容易地從轉接器10拆卸該切削主體部20。In addition, in the above description, an example of a slot (slit) is given as the screw hole 22, but as the screw hole 22, in addition to the slot, a cross slot (cross hole), a hexagonal hole, a square hole can be exemplified A well-known threaded hole such as a hole, a star hole (hexagonal star), or the like. As long as the cutting body 20 is provided with these threaded holes, it is possible to use a bit, a wrench corresponding to these threaded holes, a hand tool or an electric power tool (an impact wrench, an impact screwdriver, etc.), a screwdriver, a hexagon The cutting body 20 can be easily detached from the adapter 10 using a wrench, other hand tools, or an electric screwdriver.

在切削主體部20的外周面的從第2方向上的第2端部側到螺紋槽21之間，設置有鑽頭刃23。圖8是從第2方向觀察切削主體部20的第2端部側的平面圖。鑽頭刃23是調整在鋼板等形成的孔的直徑的鉸刀用的刃，刃的結構並沒有特別限定。然而，較佳為，在利用螺紋作用使切削主體部20固定於轉接器10之際，鑽頭刃23藉由向與使切削主體部20旋轉的方向相反的方向旋轉，而切削鋼板等。例如，當在固定於轉接器10之際使切削主體部20順時針旋轉的情況下，切削主體部20逆時針旋轉而鑽頭刃23切削鋼板等。由此，能夠防止切削主體部20在切削中途從轉接器10脫落。A drill edge 23 is provided between the second end portion side in the second direction and the thread groove 21 of the outer peripheral surface of the cutting body portion 20 . FIG. 8 is a plan view of the second end portion side of the cutting body portion 20 viewed from the second direction. The drill blade 23 is a blade for a reamer for adjusting the diameter of a hole formed in a steel plate or the like, and the configuration of the blade is not particularly limited. However, it is preferable that when the cutting body 20 is fixed to the adapter 10 by the screw action, the drill blade 23 is rotated in a direction opposite to the direction in which the cutting body 20 is rotated to cut a steel plate or the like. For example, when the cutting body portion 20 is rotated clockwise while being fixed to the adapter 10, the cutting body portion 20 is rotated counterclockwise, and the drill blade 23 cuts a steel plate or the like. Thereby, the cutting body portion 20 can be prevented from falling off from the adapter 10 in the middle of cutting.

圖9是圖6的IX-IX線處的剖視圖。在切削主體部20的外周面的位於第2方向上的螺紋槽21與鑽頭刃23之間的部分設置有平面對即第1平面24A和第2平面24B。第1平面24A和第2平面24B與第2方向平行，且相互平行，而且，在與第2方向正交的方向上重疊。通過設置有第1平面24A和第2平面24B，能夠利用扳手等夾持第1平面24A和第2平面24B而使切削主體部20旋轉。也就是說，使用扳手等工具而將切削主體部20安裝於轉接器10，另外，能夠使用扳手等工具而從轉接器10拆卸切削主體部20。此外，上述的平面對是一個即可，但也可以是多個。例如，在從第2方向觀察的情況下，也可以利用相互旋轉了60°的三個平面對形成正六邊形。FIG. 9 is a cross-sectional view taken along line IX-IX of FIG. 6 . A first flat surface 24A and a second flat surface 24B, which are a pair of flat surfaces, are provided in a portion of the outer peripheral surface of the cutting body portion 20 between the thread groove 21 in the second direction and the drill edge 23 . The first flat surface 24A and the second flat surface 24B are parallel to the second direction, are parallel to each other, and overlap in a direction orthogonal to the second direction. By providing the first flat surface 24A and the second flat surface 24B, the cutting body 20 can be rotated by sandwiching the first flat surface 24A and the second flat surface 24B with a wrench or the like. That is, the cutting body 20 is attached to the adapter 10 using a tool such as a wrench, and the cutting body 20 can be detached from the adapter 10 using a tool such as a wrench. In addition, the above-mentioned plane pair may be one, but may be plural. For example, when viewed from the second direction, a regular hexagon may be formed by three plane pairs mutually rotated by 60°.

如上述那樣，由轉接器10和切削主體部20構成的切削用前端工具1安裝於衝擊扳手而能夠進行在鋼板等形成的孔的直徑的調整(精加工)。另外，即使是在切削主體部20在切削作業中折斷了的情況下，也能夠使用一字螺絲起子而從轉接器10拆卸切削主體部20。因此，即使是在切削過程中切削主體部20的鑽頭刃23部分被折斷而僅切削主體部20的螺紋槽21部分殘留了的情況下，也能夠使用一字螺絲起子而從轉接器10拆卸殘留的螺紋槽21部分。As described above, the cutting tip tool 1 composed of the adapter 10 and the cutting body 20 is attached to the impact wrench to adjust the diameter (finishing) of a hole formed in a steel plate or the like. In addition, even when the cutting body portion 20 is broken during the cutting operation, the cutting body portion 20 can be detached from the adapter 10 using a flat-blade screwdriver. Therefore, even when the drill edge 23 of the cutting body portion 20 is broken during cutting and only the thread groove 21 portion of the cutting body portion 20 remains, it can be removed from the adapter 10 using a flat-blade screwdriver The remaining part of the thread groove 21.

而且，藉由設置有第1平面24A和第2平面24B，能夠使用扳手等工具而從轉接器10拆卸切削主體部20。由此，即使是在以手的力量無法從轉接器10拆卸切削主體部20的情況下、或者、即使是在切削主體部20的鑽頭刃23部分折斷了的情況下，也能夠通過使用扳手等工具而從轉接器10拆卸切削主體部20。Furthermore, by providing the first flat surface 24A and the second flat surface 24B, the cutting body 20 can be removed from the adapter 10 using a tool such as a wrench. Accordingly, even when the cutting body 20 cannot be detached from the adapter 10 by hand strength, or even when the drill edge 23 of the cutting body 20 is partially broken, it is possible to use a wrench. The cutting body portion 20 is detached from the adapter 10 by using a tool such as that.

此外，在上述的實施方式中，列舉衝擊扳手作為旋轉工具的一個例子而進行了說明，但旋轉工具也可以是衝擊螺絲起子等。在該情況下，轉接器10的連接部的結構可與衝擊螺絲起子相應地適當變更。In addition, in the above-mentioned embodiment, the impact wrench was mentioned and demonstrated as an example of a rotating tool, However, an impact driver etc. may be sufficient as a rotating tool. In this case, the structure of the connection portion of the adapter 10 can be appropriately changed according to the impact driver.

另外，切削用前端工具1說明為調整孔的直徑(精加工)的鉸刀，但也可以是在鋼板等開孔的鑽頭。圖10是表示變形例的切削用前端工具的切削主體部30的圖。在變形例中，也與上述實施方式同樣，切削用前端工具具備轉接器10和切削主體部30，轉接器10與上述實施方式同樣，因此，省略其說明。In addition, although the cutting tip tool 1 was described as a reamer for adjusting the diameter of a hole (finishing), it may be a drill for drilling a hole in a steel plate or the like. FIG. 10 is a view showing a cutting body portion 30 of a cutting tip tool according to a modification. In the modification example, the cutting tip tool includes an adapter 10 and a cutting body 30 as in the above-described embodiment, and the adapter 10 is the same as the above-described embodiment, so the description thereof is omitted.

The cutting body 30 can be attached to the adapter 10 using a tool such as a wrench, and a tool such as a wrench can also be used. Then, the cutting body portion 30 is detached from the adapter 10 .

而且，切削用前端工具也可以是在鋼板等開孔的鑽頭刃和調整孔的直徑(精加工)的鉸刀用的鑽頭刃成為一體的工具。圖12是表示另一變形例的切削用前端工具的切削主體部40的圖。在該變形例中，也與上述實施方式同樣，切削用前端工具具備轉接器10和切削主體部40，轉接器10與上述實施方式同樣，因此，省略其說明。Further, the cutting end tool may be a tool in which a drill edge for drilling a hole in a steel plate or the like and a drill edge for a reamer for adjusting the diameter (finishing) of the hole are integrated. FIG. 12 is a view showing a cutting body portion 40 of a cutting tip tool according to another modification. Also in this modification, as in the above-described embodiment, the cutting tip tool includes an adapter 10 and a cutting body portion 40.
